ABSTRACT:
An electronically-controlled fuel injection system for an internal combustion engine including means including a computer for electronically controlling a fuel injection quantity of an engine, means for detecting a rotational speed of the engine and a throttle sensor having lower and higher opening regions for detecting an opening of a throttle valve is further provided with means for storing the ratio between the slopes of output voltage characteristic curves derived from the regions with respect to a throttle opening in a range where the ranges of throttle openings to be detected in the regions overlap, and means for correcting the output voltage generated from one of the regions by use of the ratio in a throttle opening range exceeding said overlapping range.
